General name
Polyester filament

CLAVELLA™ is Kuraray’s trade name for polyester filament. Polyester fiber was developed in England in 1941. DuPont acquired the patent rights and began commercial production of polyester fiber in 1953. In 1969, production of CLAVELLA™ began in Saijo, Ehime Prefecture, using technology licensed from German company Hoechst AG. Polyester fiber has excellent versatility and the volume of production is increasing every year, with global production capacity reaching nearly 70 million tons in 2016. The global market share of CLAVELLA™ is 0.01%. This makes Kuraray the smallest polyester manufacturer in the world. For this reason, Kuraray makes its presence known through the production of specialized fibers, such as water-soluble fiber MINTVAL™ and conductive fiber CLACARBO™.
